useful Improvements in Hydraulic Dredges,

of which the following is a specification.

- My present invention relates to an improved device for attaching andmaintaining in position the shore discharge-pipe of hydraulic machinery,the advantages and construction of which device will be hereinafter setforth, reference being had to the annexed drawings, in which Figure 1 isa side elevation of the apparatus; Fig. 2, a top plan view of the same,certain portions being omitted; Fig. 3, a transverse section through aportion of the discharge-pipe, and Fig. 4 a top plan View of the partsshown in section in Fig. 3.

The object of my invention is to provide a suitable support for theconnection of the end of the discharge-pipe carried by the pontoon andthe corresponding end of the shore discharge-pipe. Y

In the drawings, A represents a pontoon carrying a discharge-pipe B.Secured to and extending outwardly from the upper face of said pontoonare arms or levers 0, having socured to them near the outer ends a crossor bridgefpieoe D, preferably made up of chan-. nel-bars andangle-plates, as indicatedinsection in Fig. 1. Mounted Within andextending-downwardly from said bridge-piece are two eyebolts E, adjustably secured in said bridge-piece, so that they may be raised-orlowered, as occasion may demand. Said bolts 7 are designed to form asupport for the end of the shore discharge-pipe F, being connected tosaid pipe by two trunnions G, which find their bearings in the eyes ofthe eyebolts.

Pipe F is connected to the discharge-pipe B by an intermediate flexiblesection H, of rubber or other similar material, which may, if desired,be protectedby any suitable armor. Radius-bars I are pivotally connectedto brackets J, secured to the pontoon, and at their opposite endsarelikewise connected to the trunnions G. With the construction thusdescribed the shore-pipe is free to assume any angle up to that shown inFig. 1

with the axis of the pontoon, and it is there- Serial No. 24,250. (Nomodel.)

fore necessary to make provision for minimizing the strain on the rubberconnectingsection H, as this angle varies. This is accomplished bysimply raising or lowering the eyebolts E according to the elevation ofthe shore discharge-pipe. The radius-bars I take up and thrust, whichthe weight of the shore discharge-pipe may put on the trunnions when thepipe is elevated. It is obvious that various equivalent constructionswillsuggest themselves for the details herein set forth, and I do notdesire to be understood as limiting myself strictly to those shown.

- Having thus described my invention, what I claim is- 1. In combinationwith a pontoon, a discharge pipe carried thereby; a shore discharge-pipea flexible connection intermediate said pipes; a pivotal support for theshore discharge-pipe; and means for raising and lowering said support.

2-. In combination with a pontoon, a discharge pipe carried thereby; ashore discharge-pipe; a flexible connecting-section intermediate saidpipes; a pivotal support for said shore discharge-pipe supported fromthe pontoon; and means for changing the height of said support.

3. Incombination with a pontoon; adiecharge-pipe carried thereby; ashore discharge-pipe; a flexible connecting-section intermediatesaid-pipes; a pivotal support for said shore discharge-pipe supportedfrom the pontoon; and means for relieving said inter- Y mediate sectionfrom the thrust of the shore discharge-pipe.

4. In combination with a pontoon, a dis charge pipe carried thereby; ashore discharge-pipe; 'a flexible connecting-section intermediate saidpipes; a pivotal support for said shore-pipe supported from the pontoon;means for adjusting the height of said support; and means for relievingthe intermediate flexible section from the thrust of the v shoredischarge-pipe.

5. In combination with a pontoon, a discharge-pipe carried thereby; armsor levers extending outwardly from said. pontoon; a bridge-pieceextending across between said arms; a shore discharge-pipe; pivotalconnections between said pipe and the bridge piece; thrust-barsextending from said pivtrnnnions and pivotally connected at theiropposite ends to the pontoon; and a flexible section H interposedbetween the dischargepipe on the pontoon and the shore dischargepipe.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
